Maytag dryer F4E4: l2 line voltage error
F4E4 means the control detected that one side (L2) of the 240-volt power supply is missing or very low on electric models. On gas models the documentation points to an internal connection on the main control instead.

What the dryer is detecting
Electric dryers need both legs of a 240-volt supply: one runs the motor and controls, both together run the heater. If the second leg is absent, the dryer may tumble without heat, and the control flags F4E4. Gas dryers do not use L2, so on gas models the control checks for a loopback connection on the main control.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A tripped breaker or blown fuse on one side of the 240-volt supply.
- Documented A power cord not installed correctly or not plugged fully into the outlet.
- Documented Loose relay connections on the main control.
- Possible A worn or damaged outlet or a loose connection in the house wiring.
- Documented On gas models, an unplugged or loose loopback connector on the main control.
Safe checks you can make
- Check the dryer's breaker in the electrical panel. Electric dryers use a double breaker; if either handle is tripped or sits in the middle position, switch it fully off and then back on.
- Make sure the power cord plug is pushed fully into the wall outlet and is not loose or discolored. A scorched plug or outlet is a reason to stop using the dryer and call.
- If other large appliances on the same electrical panel also misbehave, the problem may be in the house wiring; that needs an electrician.
This stage requires professional testing. Full diagnosis involves hazards such as live line voltage, gas, a sealed refrigerant system or microwave high voltage. Do not attempt it yourself.
What a technician checks
- Checks the supply at the terminal block and the relay connections on the main control.
- On gas models, checks the loopback connector on the main control.
- Testing the 240-volt supply is live-voltage work and requires professional testing.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dryer main control board replacement | $280–$640 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Use with caution. Reset the breaker and check the plug first. If the code returns, stop using the dryer: a partial power supply often points to a loose connection that can overheat.

Repair or replace?
A fault code alone rarely justifies replacing a dryer. Most F4E4 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 12–14-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
